Based on the Marvel Comics character created by Stan Lee and artist Steve Ditko. Stephen Strange beset by demons controlled by apprentice sorcerer Karl Mordo, but was rescued by Mordo’s mentor, the Ancient One, a millennia-old sorcerer who protected the Earth dimension as its Sorcerer Supreme, a role Strange was destined to inherit. He offered himself as a disciple to the Ancient One, who accepted, having known of Mordo’s treachery all along. The Ancient One spent years instructing Strange in the art of sorcery, teaching him how to tap the innate mystic powers of both himself and the world around him.
